ASSIGNOIRS 'ro THE PETERS CARTRIDGE GOMPANY, or CINCINNATI, 01110, A 0011-,

PORTION OF OHIO.

To all whom it may concern:

Be it known that-we, GEORGE'A. MUEN- ZENMAIER and FRANK M. SEE, citizens of the United States, respectively residing at Lebanon, in the county of Warren, and at Silverton, in the county of Hamilton, and

State of Ohio, hav'e invented-certain new and useful Improvements in Bullets, of which the following is a full, clear, and exact specification. f

The invention relates to that class of bullets or tprojectiles which are of conical or conoid orm arms.

Theprimary object of the invention is to produce a bullet similar to the ordinary conicalor conoid form but which will have greater velocity and steadiness in flight than bullets of the ordinary conical or conoid form.

In the ordinary conical form of bullets the forward end'of the bullet is conical and pointed, the body portion being cylindrical or approximately so, and the end or base is formed by cutting ofi the body portion on a right angles to the the body portion. This construction results in 9. bullet in which the center of gravity is much nearer the base than the oint of the bullet. T

A further o ject of the invention is to secu're an improved form of bullet in which the centerof gravity ap roaches more nearly the actual middle of t e bullet measuring from frontto rear or from point to base for it is found that an elongated rojecti e is rendered more steadyin fii ht y being so constructed than in the or inary' form of bullet described.

In the use of the ordina form of conical bullet with fiat or re ular ase as described, a vacuum'is roduce at the rear of the bullet in its fiig t'through the atmosphere'resultin in a diminishing-of its velocity, and a furt er objectsof the invention is .to se-' cure an improved form of bullet in which the tendency for a vacuum being formed at the rear or base thereof during its flight is reduced to a minimum.

A further object of the invention is to ro vide-an im 'roved form of bullet of the c ass described having a rearwardly projecting base portion, with im roved means whereby a gas check ma be ormed to prevent the escape of gases etween-the exterior of the i I I and are adapted foruse in fire- BULLET.

bullet and the inner walls of the cartridge. or shell or the inner walls of the fire arm.

A further object of the invention is to provide an improved form of bullet of the conical or conoid form in which additional or regular form and which at the same time will permit it to be loaded to a given gagelength in a cartridge of given length,-thu s germltting its use in the magazine of a gun besigned to use the regular form of a lighter u et.

To the attainment of these ends and the accompllshment of other e,w and useful obeatures of ,construction dejects, as will a pear,- the invention consists in the novel scribed in the specification, referred to more specifically in-the claims and shown in the accompan ing drawings forming a part of In said drawin Figure 1 presents aside elevation of a vbu let embodying the inven-- this speci cat on.

tion, and Fig. 2 is a longitudinal sectional view of the'same. F'g. 3 is a view in side f elevation of a metal jacketed or metal-cased bullet of the same general exterior.configura.'

tion as'shown in Figs. 1 and 2, and Fig. 4 isa view showing a longitudinal section of the same.

. From an inspection of the bullet shown In Figs. 1 and 2,-1t will be seen that it consists of'the regular-elongated form of conical or, conoid bullet with the addition of the comcal-shaped base portion 2 havin 1ts apex projecting rearwardly. It will a so be seen that the diameter of the baseof th1s eon 1- cal-shaped rearwardly extending ortion is somewhat less than the diameter 0 the body I ortion of the bullet which results In the ormation of the an lar shoulder 3. This shoulder is re arde as a very Importantfeature, for w en formed true and at ap proximately ri ht angles to the cylmdncal surface of the odyportion of the bullet,- It

forms a perfect gas check, thus preventing 100 the escape of the gases between .the bullet and the inner walls of the shell or the barrel of the fire arm. 4

In the use of bullets of the class described,

it is the common practice to furnish 'them'loo casing of a metal having a quality of hard! 11} 60 weight may be secured in a bullet of a given ness greater than lead, and is the inner core of lead. In this form the rearwardly projecting conical base portion is formed of I I portion causes the center of gravity of a ullet ofthis character to approach the actual middle of the bullet measuring from point to point, which steadies the bullet in its flight; also that the addition of this rearwardly extending base portion decreases the resistance of the bullet in passing through a resisting medium, as the air, by-decreasing the amount of vacuum created at the base during .its flight. It-is found that with a bullet of this eneral character, elevations are more regu ar and better maintained than in the use of similarly shaped bullets having the common form of flat or re ular base. Another advantage in the use 0 this improved form of bullet is that it may be loaded to the'same gage length as a bullet of the same form and length from point to base excludin the added conical base portiOn. 'ThI1S t ere-is the advantage of the added dnincreased weight found in the conical base portion over the regular bullet by permittingit at the same time to be used in the magazine designed for. the use of the regular torn; of bullet loaded to the standard gage length.

In order that the invention might be fully understood by'those skilled ingthe art, the details of the foregoing embodiment thereof have been thus specifically descr'ibedbut What we claim as new and desire to sea cure by Letters Patent isz- 1.
